currentPurchase.productId is always undefined

[hyochan]

Could you also try currentPurchase.id? Also please try the example app I've wrote in the repo 🙏

how to get the base64 encoded receipt

[hyochan]

In the managed workflow, expo-iap requires using the development client (expo-dev-client) to function properly. Without it, native modules like expo-iap cannot be included in the default Expo Go or in the EAS build without a custom dev client.

Also, the error you're encountering (AppTransaction has no member 'appTransactionID') suggests a mismatch between your local StoreKit version and what the library expects. This typically gets resolved when building with the correct native environment via dev client.

I've successfully migrated and tested expo-iap multiple times starting from Expo SDK 52, and it works fine under those conditions.

If you need further help, it’d be super helpful to have a reproducible example repo. Happy to take a look!

[jaxxcoder]

yeah we need

How to verify receipts

[hyochan]

Here is my current plan hyochan/react-native-iap#2754 (reply in thread)

and related discussion #142

[s1tony]

I am running into a similar problem, (AppTransaction has no member 'appTransactionID'), using:

React 0.79.5
Expo 53.0.20
ExpoIap 2.8.0

I am not sure how to resolve, as I am not using managed workflow.

[hyochan]

@s1tony Have you checked https://expo-iap.hyo.dev/docs/guides/faq#build-error-apptransactionid-property-not-found?

[s1tony]

Thank you! I was able to resolve it by updating Xcode to 16.4.
